Description

  The present invention relates to a power supply device, and more particularly to a device that can compensate for power shortage of a power supply that generates power using a lighting fixture.

  When a solar panel is attached to the reflector behind the lamp tube of the fluorescent lamp, the light from the fluorescent lamp is received by the solar panel, the capacitor or rechargeable battery is charged by the electromotive force of the solar panel, and the switch of the fluorescent lamp fixture is turned off. Alternatively, it has been proposed that when a fluorescent lamp is turned off, an emergency lamp or a guide lamp is energized from a capacitor or a rechargeable battery to be turned on to effectively use electric energy (Patent Documents 1 and 2).

  In addition, with the recent dramatic development of electronic technology, power-saving and high-brightness LEDs have been put into practical use, and LED lamps have been adopted instead of fluorescent lamps (Patent Document 3, Patent Document). 4).

  On the other hand, a strip-like solar panel is attached to a lamp tube that emits light when energized, or is placed so as to be at an interval of 10 mm or less, and sufficient electric power is generated by effectively using the electrical energy of the lighting, so that a storage battery or capacitor There have been proposed power supply apparatuses that can be charged and used (Patent Documents 5 and 6).

  However, although the power source devices described in Patent Documents 5 and 6 can effectively use the energy of the lamp tube, for example, it takes time to fully charge a storage battery or a capacitor, and it is necessary to start using the battery before reaching full charge. As a result, sufficient use time could not be secured.

  This invention makes it a subject to provide the power supply device which could compensate the power shortage of the power supply made to generate electric power using a lighting fixture in view of this point.

  Therefore, a power supply device according to the present invention includes a power generation lamp device that generates power by receiving light from a lamp tube of a lighting fixture (fluorescent lamp or LED light) by a solar panel, and a first power source that uses the output of the power generation lamp device as a power source. Rechargeable batteries, a solar power generation device that receives sunlight by a solar panel, a second rechargeable battery that charges the output of the solar power generation device as a power source, and a second power source that charges a commercial power source as a power source Three rechargeable batteries, an output circuit connected to the outputs of the first, second and third rechargeable batteries via first, second and third on / off switches, and the first and second rechargeable batteries. And a control device for selectively closing one of the third opening / closing switches and opening the other.

  A feature of the present invention resides in that, in addition to the power generation lamp device, a solar power generation device and a commercial power source are provided, and storage batteries are charged by each to select an output from the three. Thereby, even if it is necessary to start using the storage batteries of the power generation lamp device before reaching the full charge, it is possible to select and use the solar power generation device or the commercial power source as a power source. The usage time can be secured.

  In the above, one of the power generation lamp device, solar power generation device and commercial power supply can be selected by an external command. However, when using it as a power source for an emergency light device etc. You should be able to choose.

  Accordingly, the control device further includes first, second, and third comparison circuits that compare the charging voltages of the first, second, and third rechargeable batteries with the respective reference voltages, and the control device includes the first, second, Upon receiving the output of the third comparison circuit, among the charging voltages of the first, second, and third rechargeable batteries, the open / close switch of the rechargeable battery having a high charge voltage is closed and the other open / close switch is opened. It is preferable to provide a function.

  When a commercial power supply is used, it is necessary to provide a conversion circuit that converts alternating current into direct current. In addition, it is desirable to provide a function for preventing overcharge of the first, second, and third rechargeable batteries. For example, the above-described conversion circuit may be provided with an open / close circuit for preventing overcharge.

  The solar power generation apparatus may be configured by mounting a solar panel on a gantry, but recently, it has been put into practical use with a solar panel configured by providing a transparent power generation module on a transparent substrate. Thus, in the case of a solar panel that is transparent as a whole as described above, power generation can be performed by attaching it to a window glass of a house or the like. An opaque solar panel can also be used when pasting on a window glass.
